CORN STR-INGER.

Application filed October 24, 1921.

To 0,7? fir/1 ein if may concern.'

Be it known that l, @Hannes Mausi-i: PUT- NAM: a citizen of the UnitedStat-es`r residing` at nimm in the county of Gratiot and State of/Iichigan. have invented certain .new and useful improvements in Corndtringfers; and 'l herebyY declare that the tollowinq is a full, clear,and exact description thereof, reference being` had to the accompanyingdrawings. which form part ot the speciiication.

My invention relates to improvements in corn stringere wherebyjl amableto string' seed corn rapidly and without bruising' same.

lilly device provides 'for weavingr the corn between strings iu such a.manner that the strings are drawn taut but not tight enough to torcetheir way between the grains or bruise them.

'Referring to the d 1awings: 1 shows a vertical cross section of my cornStringer. Fig. 2 is a. horizont-al cross section on the line2-2 otFig. 1. Fig. 3 is an enlarged portion in cross section showing how thestrings .pass through the slides.

Referring more particularly to the. drawings; 10 and 11 denotecomplementary sliding` trames attached to eachother by rope 12 whichIpasses over pulley 13 which pulley is mounted on stationary 'frame 111;cross bars 15 are att-ached to this frame and slidablyv hold theslidingT frames 10 and 11 in proper relation to said stationary frame14. Sliding frame 10 is provided with horizontal bushings 16. Slidingframe 11 is provided with a screw eye 17 bent at right angies. y

A t the lower end of the sliding trame 1u is attached a weight 18 tocounterbalance a treadle 19 attached by link 20 to the lower end otslidingtrame 11. The treadle 19 swings upon hinge 20% att-ached to thesupporting trame of table 21. A coil spring 22 is attached to the table21 and the treadle 19 aiding in the quick return ot the treadle to anormal position after being depressed in operation of my device.

The slanting table 21 is secured to the stationary frame 14 by cross bar23 and slantinpsupport 24. Slightly above and'on the opposite side tromthe table 21 is tension table 25 secured to stationary frame 14 by meansof braces 26. Upon the tension table 25 are mounted four metal springSpecicaton of Letters Patent.

plates 2? which are bent so as to be held in hinge-d position by staples2S. bolt 29 passes through the table 25 through a hole provided in plate2T' and there sur- ,mounted by a coil spring' S150 held in properljustable tension by wing' nut 31. lplates 2,1 rest upon a dat metal barAttached by staples to the table 25 are guides 33, 341, 'l'and 3G. rllheguides are provided with a bent end which. keeps them from slipping out'trom between the staples in which they are hing-er and also limitthedownward motion ot the lQjuide. The outer portion oi these guides tornia loop thiioug'h which the rope or twine used in my device is threaded.rThe guides direct and also take up any slack in the twine.

ln the operation of my device four halls ot rope ortwine denotedby 37are placed upon the Aqjround or floor, the ends of said twine being'passed through'holes 38 in tension table 25. thence over the flat metalbar 32 and under spring' plate 27. 'thence the twine is threadedrespectively through the fluide 33. B41-, 35 and 3G. The twine passingthrough guides 33 and 3G is threaded through .screw eyes 1T inthesliding1 trame 11. rPhe twine passing; through guides 34 and 35isthreaded through bushings 16 pror 1vided in sliding; trame 10.

The table 21Y provided with guide rails 39. lt will be noted that at thepoint 4-1 where the operator passes the ears 0i corn denoted by #10,between the cords 9,?. this rail 39 is omitted to allow the corn to bequickly slipped onto the table. After an ear of corn has been placedbetween the cords the treadle 19 is pressed downward by the toot ot' theoperator this causes the sliding,r iframe 11, to descend and itscomplementary sliding tame 10 to rise, thus carrying; two cords up l:indtwo down, another ear of corn is then passed between the cords in theirnew position. the operator then releases the pressure of his toot andthe complementary sliding trames resume their original positionsassisted by weight 18 and spring` 22.

This operation is repeated nntil the desired number ot ears have beenstrung, the cords are cut and the strung ears are removed and placed toone side preparatory to removal to the drying house. The out ends ot thetwine are again knotted and the process again repeated.

It will be seen from the above description that the number of earsstrung per dayv is only limited b v the speed at which the operator canfeed the ears. The slant of the table 2l aids in sliding or pushing thecorn down the table when strung.

It Will further be seen that the corn may be strung as tightly asdesired by regulating the tension of springs 30 on the tension tabletogether With the pushing pressure exerted by the operator in slidingthe strung corn down the slanting table 21.

It is apparent that my device provides for Stringing the ears of cornwith even tension and that the number or' ears strung have little or anyeffect upon this tension, the Weight ot' the strung ears being supportedupon my slanting table. The ears of seed corn are strung in parallelrelation to each other there being no limit to the number that may bestrung in any one series.

It is also apparent -from the construction and plainly shown in F ig. lthat the slanting table 2l is slotted so as to permit the cords 37 topass beneath the level ol salu table on the down stroke ol the slidingframes 10 and 11 respectively. This it will be seen permits the ears ofcorn to rest upon the surface of the said table and at the same timeslide between the said cords.

Claims:

l. A corn Stringer of the class described comprising an upstandingframe, complementary sliding frames mounted therein, a rope connectingsaid Asliding frames, a pulley for supporting said rope mounted in saidupstanding frame, a tension table attached to said upstanding frameprovided with tension spring plates, bolts and springs, a slanting tableopposite said tension table and attached to said upstanding frame,

strings threaded through said tension means and passed through saidsliding frames in pairs respectively, a treadle hinged to saidl slantingtable and attached to one oi said sliding' frames and a Weight attachedto the other sliding irame whereby the movement of said treadle `willalter the relation oli said sliding frames and said Weight upon therelease ot said treadle will return said sliding frames to normalposition crossing and recrossing said pairs of string thereby Stringingears of seed corn in parallel relation.

2. A corn stringer or the class described comprising an upstandingtrame, complementary sliding trames mounted therein, a rope connectingsaid sliding frames, a pulley it'or supporting said rope mounted in saidupstanding frame, a tension table attached to said upstanding frameprovided with tension spring plates, bolts and springs, a slanting tableprovided With cord slots therein said table being located opposite saidtension table and attached to said upstand- 'ing trame, strings threadedthrough said tension means and passed through said sliding trames inpairs respectively, a treadle hinged to said slanting table vandattached toone oi said slidingframes and a Weight attached to the othersliding frame whereby the movement of said treadle will alter therelation of said sliding frames and said weight upon the release of saidtreadle will return said sliding frames to normal position crossing andrecrossing said pairs of string thereby Stringing' ears of seed corn inparallel relation. i

In testimony that I claim the foregoing as my own, I allix my signature.
